Last month, an inside source admitted that Jenelle has become "too much of a liability" for MTV. What to do? What to do?

Well, at MTV's request, Jenelle has voluntarily checked herself into a rehab facility. I hope it's better than the ineffectual rehabAmber Portwood visited on Teen Mom. Several sources have confirmed Jenelle's whereabouts… but why is she there? The answer depends on whom you ask.

RadarOnline: Heroin

A source "close to Jenelle" cashed intold Radar that Jenelle is “seeking treatment for her drug addiction issues and related stresses stemming from her tumultuous last few months."

The source cited heroin as the drug, saying, “Everyone has been worried about Jenelle doing heroin, even though she was denying that for a long time."

Friend / Attention Junkie Kristin: Protection

Kristin often serves as Jenelle's "voice" when Jenelle doesn't have access to Twitter. She obviously thrives on the attention. Kristin took to Jenelle's official Facebook fan page to announce herself as a point of contact for info about Jenelle's stay in rehab. She will answer whatever questions Jenelle's fans have via her twitter… out of the kindness of her heart… or something.

According to Kristen, Jenelle is not in rehab for drugs, bipolar support, anger management, or vaginal rejuvenation (it seriously came up!).

Want attention much? Despite her promise to say it only once, Kristin went on to say it again and again and again and again.

Kristin also tweeted, "MTV sent [Jenelle] there while this season [of Teen Mom 2] is airing" and "it's not that they don't want her watching it, MTV sent her there for, like, protection against the hateful fans and comments."

Boyfriend / Dog Sitter Gary: Emotional Support

"Jenelle is NOT ON DRUGS. She got sent for emotional support because this season [of Teen Mom 2] was so intense," Gary tweeted. "MTV does not want her to see this season and then relapse BC of all the stress."

Gary added, "Jenelle does not do drugs. I won't allow that. She knows that if she ever goes back to drugs then she can have them but she won't have me. I won't allow it."
